This paper attempts to explain some of the salient piping activities
(along with their sequence) and interaction with other disciplines
during detail engineering. Piping Engineers and Designers may find some
of it too rudimentary. This is deliberate. The constraints have not been
touched upon. Moreover, any single write-up based on a typical job
cannot do justice to vast number of activities that a piping team performs.
1. Development of Equipment Layout:
This is arguably the most challenging single activity because almost all
input except Process P&IDs and Engineering Design Basis is fluid. The
challenge involves creativity, ability to draw upon experience of
similar jobs, provisioning for unexpected changes and resolving often
conflicting requirements. The major inputs and points considered are:
a. Plot Plan with clear demarcation of Units
b. Process P&IDs and PFDs (Utility Distribution P&IDs are received later
because these are based on equipment layout).
c. Indicative Layout, if available (normally for Licensor Units)
d. Engineering Design Basis
e. Statutory Requirements
f. Tentative Dimensions of Equipments/ Packages
g. Connectivity and Access for Maintenance and Erection
h. Critical Piping Circuits e.g. Transfer Lines and Reboiler Lines
i. Aesthetics
The equipment layout thus prepared is sent to almost all major
disciplines and Client for their comments. These comments are then
consolidated and the conflicting ones are discussed across the table.
The layout is now ready for dissection by core group of senior piping
people, and this experience of being grilled and cross-examined is a
ritual that signifies coming of age of a piping engineer. Changes which
affect others are once again taken up with respective disciplines. This
layout is then put up for Apex Review. The approved version is the basis
for further engineering by Piping and many other disciplines e.g.:
Structures: for Foundations and Super-structures
Instrumentation: for Cable Routing
Electrical: for Area Classification and Trench Routing
General Civil: for Pavement Drawing
Process: for Development of Utility P&IDs
Construction: for Erection Planning, Hard Stand Arrangement, etc.
Cross-reference purpose by many e.g. an SED Engineer while preparing his
input for Mechanical Tender would need to refer to this Layout for Levels.
2.Zone/Area Division:
The approved Layout is divided into areas (Area Division). While the old
concept of an area was what an A0 size drawing could cover in a
particular scale (and this concept has its merits), the trend in this
era of 3-D Modelling has shifted to zones. A particular zone covers
synergic specific areas e.g. a particular Tech Structure would be
covered in a single zone instead of three or four areas. Similarly, one
may find the whole pipe-rack of a medium sized unit carved in two zones
instead of eight to ten areas. Once this division is over, specific
area/zone wise responsibilities are assigned for Studies, Modelling, MTO
and Flexibilty Analysis. This is also the time when team formation takes
place.
3.Piping Studies:
The adage that piping study is ‘half science and half art’ is true. The
art part is visualization and creativity while science refers to
following the established norms; however, what is forgotten is that a
piping study involves lot of dedication, risk-taking ability and
discipline. A piping designer is at work 24 hours. A good scheme,
solution or an alternate striking at midnight is not uncommon, something
akin to Archemides and Eureka! Many a times the designer would also have
to release fronts for downstream users even when the input is still
coming and then he must constantly be on the vigil for changes in input.
A good designer knows not only how he is affected by others but also how
his work affects others. By-products of a piping study are:
a. Confirmation/comments on Structural Foundations and Super-structures
(this also involves additional associated information e.g. openings,
brackets, loads, bracings, approach, etc).
b. Confirmation/Comments on Locating Dimensions (including Centre-line
and Bottom Tangent Line Elevations) of Equipments.
c. Miscellaneous platforms – connecting ones (including walkways),
independent ones and the ones required on equipments (the latter enables
Istructures to release platform cleats).
d. Comments on Setting Plans of Exchangers – identification of fixed
support, saddle-to-saddle distance, orientation of davits, pipe clips,
piping loads on nozzles, etc.
e. Comments on Air-cooler Setting Plans
f. Comments on Mechanical Datasheets – identification of fixed support,
davit arm length and height, pipe clips.
g. Nozzle Orientation of Columns and Vessels
h. Comments on Compressor and Pump Drawings
i. Firming-up of interface for packages e.g. for Dosing Skids, Heaters
(Burner Piping), Chillers, Ejector Systems, etc.
j. Firming-up of route of Instruments Cable Trays, Electrical Trenches, Fire-water system
k. Battery-limit interface
l. Front for 3-D Modelling (recently, some of the simpler layouts are directly being attempted on 3-D)
m. Preliminary and part of Intermediate MTO
n. Front for Flexibility Analysis
4.Piping MTO:
Material Take-off is usually done in three stages (Preliminary,
Intermediate and Final), followed by Top-up, if required. The time-line
typically is beginning of the project (just after issue of Equipment
Layout), middle of the project (around 50-60% piping progress) and
towards final stages of engineering (over 90% piping progress). The
first one is a total manual affair and the emphasis is on long delivery
items. For intermediate MTO, material dump is taken from Model and the
balance is made up manually, while the final MTO is almost totally taken
from Model. Material substitution is also used to the extent possible in
order to control surplus generation. Relative merits and constraints of
roll-on MTO vis-à-vis the conventional mode have been discussed within
and outside the department, and are still a matter of debate.
An integrated state-of-art software called IPMS has been developed
in-house (by ITS with active help from user departments) and this caters
to MTO Processing and almost all related downstream activities e.g.
Material Requisitions, Preparation of TBAs, Purchase Requisitions and
Material Control Functions right up to issue of material and maintaining
records at site. (In fact, IPMS also caters to some of the upstream
activities e.g. preparation of PMS and VMS).
MTO is followed by preparation of Material Requisitions, evaluation of
offers and issue of Purchase Requisitions. Hardcopies days are over, and
the new interface is through PDF files in a CD. Some Piping MRs involve
input from other departments (e.g. from Electrical for MOVs); in this
case, Piping acts as a coordinator too. For some items e.g. special
valves, expansion joints, etc., vendor drawings are received, commented
upon and approved.
5.Mechanical Tender:
The intermediate MTO (some times even the preliminary one) forms the
basis for piping part of Schedule of Quantities. While most of it has
been automated through the IPMS Package, some special requirements have
to be fed in manually. The other departments that piping receives input
from are Static Equipment (including Heat Exchangers), Rotating
Equipment, Package Equipment, Civil/Structures, Instrumentation, etc.
Again, all exchange within EIL and with potential contractors is through
soft files only. The related activities involve answering to vendors’
queries, attending pre-bid conference and evaluation of offers
(preparation of TBA).
6.3-D Model:
The two popular platforms are PDS and PDMS and lot of customization and
efforts have gone into reaching the stage that we are at. While for most
of the jobs, Piping and Structures have been the only ones involved,
Instrumentation and Electrical have also been attached in few jobs.
Apart from modeling Lines, Piping also models equipments. At present,
Structure is being modeled to facilitate clash detection and review of
model (this means that structural deliverables are not being taken from
3-D) and the P&IDs are not yet available on these systems in EIL.
Modelling does initially take more time but the rewards are generous:
a. Excellent Visualization
b. Detection of Clash
c. Isometric and GAD generation from Model
d. Correct MTO
e. Client Review from Operability and Maintenance point of view
f. Preservation of Model and Records for future
7.Flexibilty Analysis and Supporting:
The circuits are taken up for analysis in order of criticality i.e. the
critical the circuit, the earlier it is taken up. Criticality is a
function, among other things, of size/ temperature of line and
sensitivity of connected equipment. Other considerations like two phase
flow, wind and seismic requirements too play a part.
The tools most often used for formal analysis are Caesar, AutoPipe and
oodles of supporting sense. In fact, a good designer anticipates the
needs of stress and support engineer and saves lot of hours and
rerouting by interacting with the latter at right time. It is important
too for continuous dialogue between Piping team members and their
structural counterpart for supporting arrangement and loads.
8.Other activities:
There are many other activities that a piping engineer undertakes but
which could not be touched upon (due to paucity of time and space):
a. Interaction with Process Licensor including review of P&IDs
b. Preparation of Piping Design Basis
c. Manhour Estimates, Scheduling and Progress Reporting
d. Piping Material and Valve Material Specifications
e. Ensuring compliance with Procedures, Work-instructions and Check-lists
f. Under-ground Piping
g. IBR Package
h. Painting and Insulation Tender
i. Input to other Tenders e.g. Civil/Structural Tender
j. Arranging 3-D Model Review by Client/PMC
k. Issue of Design Change Requests/Notes and Manhour Change Orders
l. Input for Package Units and Review of Documents/Drawings of Package
Vendors
m. Record keeping and importance of Document Control e.g. maintaining indices
n. Site interface and support/co-ordination
o. Trouble shooting
p. Revamp Jobs
q. Standardization (e.g. Updation of Specifications, Technical Notes,
databank for Deviations granted, ensuring latest supply of Codes and
Standards, Technical Evaluation of New Vendors, etc.)
r. Managing a team of twenty to thirty people, keeping them motivated and
making them feel important
s. Interacting with almost all major disciplines and resolving input
conflicts
Summing Up
Piping in a plant has often been compared to arteries in human body. The
connectivity, and hence the coordination, done by a piping engineer is
enormous. In fact, there would hardly be a department not having
interface with piping. This can also be gauged from the fact piping
consumes almost half the engineering manhours of setting up of a typical
refinery, petrochemical or gas unit. Appreciation of piping sequence of
work by others and knowing how & where do their inputs fit in shall
result in better quality deliverables.

STANDARD MATERIALS THAT USE FOR PLUMBING SYSTEM
STANDARDS
Standards are sets of rules that outline specification of dimensions, design of operation, materials and performance, or describe quality of materials, products or systems. These standards should cover the performance expectations of the product for particular applications, as well as, in the case of drinking-water contact, the chemicals that may be leached from the product into the water. The intent of standards is to provide at least minimum quality, safety or performance specifications so as to ensure relatively uniform products and performance, and to remove ambiguity as to the suitability of certain commercial products for particular applications. They reduce the risk of error by installers, and also provide assurance to the plumbing system owners. Standards also provide direction to manufacturers in respect to the expectations of the products that they produce. Internationally accepted standards provide economies to both the manufacturer and the user by reducing the number of products of the same type that must be produced. Standards may be developed by industry, non-profit organizations or trade associations, as well as national or international bodies. The existence of credible standards and certifiers relieves the regulatory authority of the need to develop its own case-by-case standards and product assessment system.
The existence of a standard does not always ensure that all available products meet a specific standard. In order to be confident of uniformity in a product there must be checks and balances. This is accomplished by assessment conformity. Assessment conformity, product listing and certification all have the same meaning. Simply stated, it means that a product, material or device has been tested and verified to meet the specification that has been developed. There are at least three types of certification: where the manufacturer or seller self-certifies and guarantees the product by warranty or contract; where the manufacturer or seller obtains verification by a contract laboratory; or where the specific commercial product (not just the class of product) has been evaluated by a credible independent third-party testing or certifying organization that is in no way related to or a part of the manufacturer or seller, and which has a system for policing the validity of its certifications.
Assessment conformity, by any name, means that a product, service, material, system, device or component has undergone testing to ensure it meets theintended standard for such product, material, system, device or component. There are several organizations that perform assessment conformity and, in most cases, if a specific product, material, system, device or component meets a designated standard, the testing organization may allow placement of a mark or logo of the organization on the product, material, system, device or component to certify that the relevant standard was successfully met.
PRODUCT AND MATERIAL USING N PLUMBING
10.2.1 Standards for plumbing products and materials
The durability of a plumbing system is dependent on the quality of its component parts and the assembly skills of those who install it. No plumbing system, however well designed, can be expected to operate safely or hygienically if the products or materials used are unsatisfactory. The inverse is also true – if the best-quality products or materials are used but are installed incorrectly, the system will be a failure.
Most industrialized countries have national standards or codes that set out the minimum requirements for the material specifications, design and use of specific plumbing products. However, plumbing codes of practice vary considerably according to the extent to which they specify the detailed standards for plumbing products and other matters. Some countries take the view that the level of detail should be minimized, whereas others are very prescriptive. However, even prescriptive codes should allow for the introduction and innovative use of promising new products, materials and installation practices without undue delay. Countries that are members of the International Organization for Standardization (ISO) may choose to adopt the ISO framework as a minimum standard set for plumbing products and materials. WHO Guidelines for Drinking-water Quality should be used as reference in decisions concerning health-related matters. Several national and international standards and certifying organizations utilize and expand upon those basic principles by identifying specific products that comply. It is important to ensure that commonly used plumbing products and materials are of the same type, at least throughout a country, to take advantage of economies of scale in manufacturing and to ensure easy accessibility.
The process of certification of quality of plumbing products may necessitate the setting up of testing establishments where products can be assessed. In many cases it will be more economical to simply adopt an existing qualified standards and certification programme that already has international acceptance. This will also avoid unnecessary proliferation of standards. Product certifiers and their testing facilities must be of the highest standard and subject to external auditing.
The application of suitable materials and products must be supported by adequate levels of training of plumbers who use them so that they can identify and use only appropriate products.
10.2.2 Selecting suitable products
Numerous standards and certification bodies exist nationally and internationally, so it may not be necessary for a country to develop a unique set of standards. It could decide to adopt one of the existing systems and require that products are certified to meet that system’s requirements. In judging a product or material, the regulating authority (or certifier) must consider factors such as the following:
• Is the product or material under consideration suitable for the application or purpose?
• Will it be harmful to the health of the community in its normal use?
• Is there a risk of these materials being released into the environment (e.g. the water) in the first instance or after the working life of the product or material has expired?
All pipes, valves, taps and other fittings used for the supply of drinking-water or the removal of wastewater must not contain harmful substances above the specified amount that could leach into the water. Lead, cadmium and arsenic are examples of many possible contaminants that could be present. The pipes, valves, taps and other fittings must be capable of conveying water at a nominated pressure within a prescribed environment, and must be of sufficient strength to contain anticipated internal pressures. They must also be able to withstand external pressures if they are to be buried. The impact of environmental factors such as heat, cold, expansion, contraction, corrosion, pH and bacteria levels also need to be considered.
WHO and many national authorities have developed guidelines or standards that set out the maximum acceptable levels of metals and chemicals and other contaminants in public drinking-water supplies (WHO 2004a). These are then converted to apply to contaminants that may leach from the fixtures and the associated network of piping systems. For example, a pipe standard might require that the leaching level of a heavy metal must not exceed 10% of the drinking-water standard based upon a standard test that simulates use and exposure conditions. Some authorities also insist that piping systems for soil and waste-water drainage systems comply with the same material criteria. Manufacturers in these areas are obliged to comply or risk losing market share or perhaps face prosecution. The standards set for materials in contact with drinking-water are minimum requirements and are based upon a specified use condition range; for example, a product suitable for a cold water system will, in most cases, not be acceptable for a hot water system. It is common for piping and construction materials, as well as the water being conveyed, to be seriously affected by aggressive environments and local conditions. In summary, it is still very much in the hands of the individual project adviser or installer to ensure that the plumbing products and materials selected for the application are in accordance with officialrequirements, will not be unduly affected or influenced by local factors and are correct for the application.
As well as deciding what is an acceptable plumbing product or material, the water authority or governing organization must set standards for the level of training attained by the installation personnel, a point that cannot be over-emphasized. In some countries, for reasons of economy, transport, proximity to manufacturing plants or restricted access to international markets, the choice of available materials for plumbing products and piping systems is often limited. Socioeconomic reasons may also dictate the quality and standard of plumbing in domestic dwellings.
10.3 Metallic and non-metallic materials used in pipework
There are two families of materials available for water pipework systems: metallic and non-metallic materials. Of these the most commonly used materials for drinking-water supply piping are galvanized steel or iron, copper, polybutylene, unplasticized polyvinylchloride (PVC), chlorinated polyvinylchloride (CPVC) and polyethylene (PE). Metal alloys, which far exceed the performance specifications of their respective parent materials, are also widely used. New materials and construction technologies are continually being developed for the building industry and the plumbing industry. Without some form of control at the respective levels within the plumbing and building industries it would be easy for unscrupulous manufacturers to use inferior materials to the detriment of installers and end-users. This can ultimately damage the environment and the health of the community and lead to greater costs later when systems fail prematurely.
10.3.1 Galvanized steel or iron
Galvanized steel or iron was the traditional piping material in the plumbing industry for the conveyance of water and wastewater. The term “galvanizing” once referred to hot dipped galvanizing, in other words total immersion in molten zinc after pretreatment cleaning. This technology afforded a reasonable level of internal and external protection to the metal pipe. In more recent times, the use of electroplating technologies has provided a more attractive external finish, but little or no internal protection. Although still included in many codes of practice throughout the world, the popularity of galvanized piping is declining. It is still being used extensively in the fire protection industry, but overall there are increasing limitations on how and where galvanized piping may be used. Internal and external corrosion is a particular problem where galvanized steel or iron piping is connected to dissimilar materials, such as copper alloy (brass) in taps and valves. Internal corrosion can add iron, which causes an undesirable taste and may also cause unsightly precipitation of iron salts on clothes. Aesthetic guidelines contained in the WHO Guidelines for Drinking-water Quality address these matters.
The use of galvanized steel or iron as a conduit for drinking-water is a greater problem where the water flow is slow or static for periods of time due to rust discoloration caused by internal corrosion. Galvanized steel or iron piping may also impart an unpalatable taste and smell to the water conveyed under corrosive conditions. Galvanized steel piping systems are generally accepted for outdoor use, but because of the size or bulk of the pipe and fittings, and the inflexibility of such systems overall, the material is not desirable for internal water plumbing. Galvanized pipe is heavy to handle and is generally joined by threading and screwing the components together. This is a lengthy procedure when compared to the assembly of competing non-metallic pipework systems.
10.3.2 Copper tubing
Copper tubing is extremely flexible in the hands of a competent installer and smaller in overall diameter than the equivalent galvanized steel pipes and fittings. Corrosion can be a problem, though usually to a lesser degree than with galvanized steel; care must be exercised to avoid contact with dissimilar metals. Copper tubing, due to its thinner wall section, is relatively light to handle and is available in coil form or straight lengths as required. When assembled and installed correctly it can blend into building structures without difficulty. Piping systems can be assembled with the aid of compression fittings, couplings, or by lead-free solder or brazing. A high degree of skill is required of installers who perform braze welding. Compression fittings are much simpler, but may be obtrusive.
Copper tube or pipe is also particularly useful for hot water supply systems. However, heat loss can become an issue if adequate insulation is not provided. As with all metallic materials, the risk of electrolytic corrosion should be considered. This occurs most commonly where galvanized steel pipes or fittings connect with copper alloy (brass) fittings.
System designers must be aware that water flows through copper tube piping systems must not exceed 3 metres per second. When this occurs there is a high risk that the internal bore of the piping system will be eroded by high flow and velocity scouring. Due to its electrical conductivity there is a need for care to ensure that grounding connections are separated from piping systems and any electrical wiring.
10.3.3 Polybutylene
Polybutylene in non-metallic piping systems is becoming accepted as a suitable material for the conveyance of drinking-water in domestic dwellings in some industrialized countries. However, it is banned by plumbing codes in USA due to problems with leaks at joints resulting in significant water damage in dwellings. It is a light, flexible material that is easy to handle and install. It can be usedin domestic dwellings for both hot and cold water supplies. Caution must be exercised as it can suffer degradation if exposed to excessive pressure and temperature, and exposure to ultraviolet light (sunlight) is also detrimental to the material.
There are several jointing systems available for the connection of polybutylene pipework systems, including electrofusion and socket fusion welding and a variety of mechanical jointing methods. Some mechanical joints rely on an integral grab ring while others have a compression-type joint, via a nut or a compression crimp ring or band. Some jointing systems comprise metal in-line as well as end-of-line fittings, which may not be appropriate in some locations or conditions. Polybutylene pipe is generally available in straight lengths up to 6 metres or coils 60 metres in length.
10.3.4 Chlorinated polyvinylchloride (CPVC)
CPVC is widely used in water and sanitary systems for hot and cold water distribution. It is a thermoplastic produced by polymerization of vinyl chloride, with additional chlorination. CPVC piping is manufactured by extrusion methods in sizes of diameter 0.25 inch (0.635 centimetres) to 12 inch (30.5 centimetres) in Schedule 40, Schedule 80 and standard dimension ratio (SDR) dimensions.1 It is manufactured to copper tube size (CTS).2 It offers much better resistance to corrosion and has a high tolerance to acids. It is fire resistant, though toxic fumes are emitted when it is burned. CPVC is lightweight, non-toxic and odourless, and reduces growth of fungi, algae and bacteria. It is designed to withstand continuous operating pressure of 600 kPa at a temperature of 95 ˚C. Pipe and fittings are readily cut, and joined by solvent welding.
10.3.5 Unplasticized polyvinylchloride (PVC)
PVC, when used with a solvent cement jointing system, is comparable in bulk to galvanized steel or iron for drinking-water piping, but much lighter. It does not suffer the same corrosion problems internally or externally as does galvanized steel. However, it is susceptible to physical damage if exposed above ground and it becomes brittle when exposed to ultraviolet light. The pipe is light to handle, but it is too bulky for aesthetically acceptable internal use in domestic buildings. It is used extensively around the world for drainage (waste or soil and storm water) applications.
PVC is available with a solvent cement or rubber (elastomeric) ring jointing system for internal or external drainage systems. Caution must be exercised when using PVC close to water heaters and similar heat sources. In addition to the inherent problems associated with the expansion and contraction of PVC, the material will soften and deform if exposed to a heat in excess of 65 °C.
10.3.6 Polyethylene (PE)
PE pipes and fittings of numerous types and designs have been available for over forty years. The market requirements today have been refined to three general groupings, as follows:
High-density PE is available in a post-manufactured stress-relieved state (best-practice PE), or as extruded product with no treatment. It is used mainly for drainage applications where it can withstand higher temperature discharges than PVC. To avoid ovality and installation problems when laying to grade the pipe is best used in straight lengths, normally up to 6 metres long. Jointing is achieved by electrofusion or butt-fusion welding or with compression-type joints for smaller diameter pipes and fittings.
Medium-density PE is more flexible than the high-density pipe. It has a slightly thinner wall thickness and is capable of withstanding higher internal pressure. It is the preferred material for long-distance drinking-water piping. Because of the application and the robust nature of the material it is generally available in coils of up to 200 metres (650 feet) length, depending upon the diameter. The method of jointing is the same as for high-density PE pipe. In colder climates coiled polyethylene piping can be very difficult to use and may be impractical.
Low-density PE is suitable for the irrigation industry, where operating pressures are very low and a high degree of flexibility and low cost is required. Low-density PE pipe and fittings are not acceptable for use for connection to the water mains in many countries because of the low pressure rating of the material and its high leakage rate.
10.4 General issues related to use of plastic piping
There are numerous composite PE piping systems available and new plastic materials are constantly being developed. Each must be considered on its merits for the particular application in hand. In some types, the molecular structure is cross-linked to attain a stronger product with a reduced wall thickness, allowing savings in the amount of raw material needed. Combining different types of raw material together with lamination, overlay extrusion or simply adding selected reinforcement into the extrusion process can further enhance specific qualities of the structure of the material to make it more acceptable for use in both domestic and specialized plumbing applications.
Providing that the health, safety and durability standards are met, pipes and fittings manufactured from plastic materials have many advantages for use in both hot and cold water plumbing systems. They are light, easily handled and transported, and require fewer joints than metal pipes when available in long lengths. Pipes and fittings manufactured from plastic materials may cost more to purchase than metal pipes or tubes and their ancillary fittings, but the time spent installing a plastic pipe system is generally much less than a metallic system and this may result in overall savings.
Where a large project is to be undertaken, it is not uncommon for a plastic pipe manufacturer to bring in moulding or just extruding machines with the appropriate dies, tooling and raw materials, and commence manufacturing in close proximity to the market or project site. This in turn can bring about savings in transportation and handling costs. Long delays in supply can also be averted, resulting in rapid on-site progress. Sometimes only the pipe is made at the remote locations due to its bulk, and fittings, especially when there is a large and varied range, are brought in separately.
It is important for plumbing systems that different pipe types remain separated and not intermixed with similar products. For example, rainwater or storm water drainage pipes and fittings should not be used for sanitary plumbing (soil, waste or vent pipe) applications. They have a thinner wall section and are not designed for higher temperatures or deeper than near-surface and above-ground applications where durability is not a major concern. Conversely soil, waste and vent pipes and fittings could be used for rainwater or storm water, but they are unnecessarily expensive for those applications.
Some standards and codes call for different-coloured pipes and fittings to define the designated application of the product and to assist installers, as well as for future identification to prevent cross-connections. For example, PVC pipe and fittings are easily manufactured in various colours; other materials that are not so easy to colour may rely on a stripe of colour set onto the pipe during extrusion or painted bands and labels applied after installation, with specific markings or instructions with regard to fittings, etc. Other authorities, such as electricity and gas providers, may also utilize colour coding for their buried pipelines. To avoid confusion care should be taken to coordinate the identification strategies or policies for all pipes and services.
10.5 Earthenware pipes
Earthenware is also referred to as glazed stoneware, terracotta or vitrified clay. Furnace-baked earthenware has been the most commonly used material for under-ground drainage systems. It can be locally produced in almost any country provided there is a source of good-quality clay and an energy supply to fire it. In the past, glazing was achieved by throwing salt into the fire towards the end of the firing process. This method of salt glazing damages kilns and does not
always create an even finish or glaze. Advanced material and management technologies, combined with the use of sophisticated tunnel kilns, have in recent years seen the emergence of a completely new generation of vitrified earthenware pipes and fittings of a quality previously unattainable. They are chemical and temperature resistant with elastomeric jointing couplings. The high cost currently precludes their use in domestic dwellings, but there are many special commercial or industrial applications.
Installing old-style earthenware drainage systems is difficult and maintenance is demanding because of breaks and blockages. The inherent rigidity of the system can cause the pipes to break loose at the joints or cause the pipe itself to break close to the joint just behind the collar. Tree roots can grow into the open joint or broken pipe and will eventually block the drain. In some cases groundwater can infiltrate the drain, causing the system to become overloaded. There is also the risk of contaminating the groundwater by the leakage of raw sewage from the broken joint or pipe. A further disadvantage is that earthenware pipes are heavy to transport and expensive to install compared to lighter materials such as plastics.
Plastic, mainly PVC, is now the most commonly used material for drainage systems for the conveyance of sewage and wastewater from dwellings. Other materials, such as cast iron, ductile iron, copper, fibre cement and vibrated concrete, are sometimes used for drainage systems. Each has its strengths and weaknesses; their longevity in service is dependent on how well they are installed, the nature of the water or other materials passing through them, and the installation environment.
10.6 Design of plumbing fixtures
Both the component materials and the design of plumbing fixtures (baths, washbasins, sinks, tubs, toilet pans, etc.) should be subject to standards and certification to ensure integrity and safety. Fixtures should be free of sharp projections and sharp corners that may cause injury. In order to prevent drainage sewer gases from entering the area where the fixture is installed, a fixture trap should be incorporated into the fitting, or provision should be made for fitting one at a later date. To protect the drinking-water supply, all plumbing fixtures should be designed so as to ensure that incoming water is delivered through an air gap. Tapware should be appropriately matched to the fixture that it is intended to serve. When installed, all taps and water delivery outlet fittings should have an adequate clearance between the water outlet and the spill level or water overflow level of the fixture being served. It is possible for the overflow on any fixture to become blocked, which would compromise the air gap by not leaving the correct clearance. In situations where a portable or flexible hose or tube is attached to the water outlet, and an air gap cannot be provided, an appropriate backflow prevention device should be installed in the pipework supplying the fixture.
Local usage and customs should be considered when assessing plumbing requirements. An example is the choice of pedestal toilet bowls or squats. It may also be necessary to conduct training sessions in the use of particular fixtures to ensure that they are maintained in a satisfactory and hygienic state. In some areas it is customary to provide a drinking-water supply tap adjacent to the toilet fixture to facilitate personal ablutions. In such cases strict precautions must be taken to prevent contamination or cross-connection with the drinking-water supply system.
10.7 Sanitary fixtures
Sanitary fixtures should be durable, smooth and impermeable to water. There should be no hidden surface that can become fouled or polluted. Both internal and exposed outside surfaces should be accessible for cleaning. The most common and most economical material for domestic fixtures such as toilet bowls, urinals, and washbasins is vitreous china. For more durable day-to-day use in kitchen sinks and laundry tubs, stainless steel is recommended, but enamelled pressed steel and suitable plastic materials may be acceptable.
Plastics are commonly used for bathtubs, shower trays, laundry tubs, cisterns, washbasins and toilets and are often reinforced with fibreglass for extra strength and durability. Plastic materials, although generally durable in themselves, are readily prone to surface damage such as scratches and cuts. Stainless steel is a preferred material for plumbing fixtures where there is a risk of damage from users, such as in institutions and public amenities. Stainless steel is currently the only suitable choice in commercial or industrial food preparation areas.
10.8 Concrete products
The manufacture of plumbing products of any kind is expensive because of the capital investment in plant and the associated tooling. Unless high production volumes are anticipated, it is often more economical to import such items. To save foreign currency, materials such as concrete can be used for the local manufacture of fixtures for some domestic applications. These products are inferior to those discussed above, but they may be a realistic option. Ideally, concrete products should be designed so that angles, both internal and external, are rounded for ease of cleaning, and outlet pipes may be integrally cast into the body of the fixture. Concrete fixtures should be restricted to shower trays and baths, and possibly laundry fixtures such as troughs. It is recommended that concrete fixtures be cast in place wherever possible to eliminate the need for transportation. Concrete should not be approved for kitchen or food preparation sinks or benches. Local codes should cover all probable issues involving concrete fixtures, general design principles, etc., and also specify the proportions of sand, aggregate, cement and water required with general mixing, placement and finishing instructions. Preliminary investigations should ascertain the availability of local materials of the appropriate quality to ensure that the products can be produced satisfactorily. Concrete products cannot be made completely impervious; surface treatments such as ceramic tiles are sometimes used to address this problem.
Sources : Health Aspect of Plumbing
Standards are sets of rules that outline specification of dimensions, design of operation, materials and performance, or describe quality of materials, products or systems. These standards should cover the performance expectations of the product for particular applications, as well as, in the case of drinking-water contact, the chemicals that may be leached from the product into the water. The intent of standards is to provide at least minimum quality, safety or performance specifications so as to ensure relatively uniform products and performance, and to remove ambiguity as to the suitability of certain commercial products for particular applications. They reduce the risk of error by installers, and also provide assurance to the plumbing system owners. Standards also provide direction to manufacturers in respect to the expectations of the products that they produce. Internationally accepted standards provide economies to both the manufacturer and the user by reducing the number of products of the same type that must be produced. Standards may be developed by industry, non-profit organizations or trade associations, as well as national or international bodies. The existence of credible standards and certifiers relieves the regulatory authority of the need to develop its own case-by-case standards and product assessment system.
The existence of a standard does not always ensure that all available products meet a specific standard. In order to be confident of uniformity in a product there must be checks and balances. This is accomplished by assessment conformity. Assessment conformity, product listing and certification all have the same meaning. Simply stated, it means that a product, material or device has been tested and verified to meet the specification that has been developed. There are at least three types of certification: where the manufacturer or seller self-certifies and guarantees the product by warranty or contract; where the manufacturer or seller obtains verification by a contract laboratory; or where the specific commercial product (not just the class of product) has been evaluated by a credible independent third-party testing or certifying organization that is in no way related to or a part of the manufacturer or seller, and which has a system for policing the validity of its certifications.
Assessment conformity, by any name, means that a product, service, material, system, device or component has undergone testing to ensure it meets theintended standard for such product, material, system, device or component. There are several organizations that perform assessment conformity and, in most cases, if a specific product, material, system, device or component meets a designated standard, the testing organization may allow placement of a mark or logo of the organization on the product, material, system, device or component to certify that the relevant standard was successfully met.
PRODUCT AND MATERIAL USING N PLUMBING
10.2.1 Standards for plumbing products and materials
The durability of a plumbing system is dependent on the quality of its component parts and the assembly skills of those who install it. No plumbing system, however well designed, can be expected to operate safely or hygienically if the products or materials used are unsatisfactory. The inverse is also true – if the best-quality products or materials are used but are installed incorrectly, the system will be a failure.
Most industrialized countries have national standards or codes that set out the minimum requirements for the material specifications, design and use of specific plumbing products. However, plumbing codes of practice vary considerably according to the extent to which they specify the detailed standards for plumbing products and other matters. Some countries take the view that the level of detail should be minimized, whereas others are very prescriptive. However, even prescriptive codes should allow for the introduction and innovative use of promising new products, materials and installation practices without undue delay. Countries that are members of the International Organization for Standardization (ISO) may choose to adopt the ISO framework as a minimum standard set for plumbing products and materials. WHO Guidelines for Drinking-water Quality should be used as reference in decisions concerning health-related matters. Several national and international standards and certifying organizations utilize and expand upon those basic principles by identifying specific products that comply. It is important to ensure that commonly used plumbing products and materials are of the same type, at least throughout a country, to take advantage of economies of scale in manufacturing and to ensure easy accessibility.
The process of certification of quality of plumbing products may necessitate the setting up of testing establishments where products can be assessed. In many cases it will be more economical to simply adopt an existing qualified standards and certification programme that already has international acceptance. This will also avoid unnecessary proliferation of standards. Product certifiers and their testing facilities must be of the highest standard and subject to external auditing.
The application of suitable materials and products must be supported by adequate levels of training of plumbers who use them so that they can identify and use only appropriate products.
10.2.2 Selecting suitable products
Numerous standards and certification bodies exist nationally and internationally, so it may not be necessary for a country to develop a unique set of standards. It could decide to adopt one of the existing systems and require that products are certified to meet that system’s requirements. In judging a product or material, the regulating authority (or certifier) must consider factors such as the following:
• Is the product or material under consideration suitable for the application or purpose?
• Will it be harmful to the health of the community in its normal use?
• Is there a risk of these materials being released into the environment (e.g. the water) in the first instance or after the working life of the product or material has expired?
All pipes, valves, taps and other fittings used for the supply of drinking-water or the removal of wastewater must not contain harmful substances above the specified amount that could leach into the water. Lead, cadmium and arsenic are examples of many possible contaminants that could be present. The pipes, valves, taps and other fittings must be capable of conveying water at a nominated pressure within a prescribed environment, and must be of sufficient strength to contain anticipated internal pressures. They must also be able to withstand external pressures if they are to be buried. The impact of environmental factors such as heat, cold, expansion, contraction, corrosion, pH and bacteria levels also need to be considered.
WHO and many national authorities have developed guidelines or standards that set out the maximum acceptable levels of metals and chemicals and other contaminants in public drinking-water supplies (WHO 2004a). These are then converted to apply to contaminants that may leach from the fixtures and the associated network of piping systems. For example, a pipe standard might require that the leaching level of a heavy metal must not exceed 10% of the drinking-water standard based upon a standard test that simulates use and exposure conditions. Some authorities also insist that piping systems for soil and waste-water drainage systems comply with the same material criteria. Manufacturers in these areas are obliged to comply or risk losing market share or perhaps face prosecution. The standards set for materials in contact with drinking-water are minimum requirements and are based upon a specified use condition range; for example, a product suitable for a cold water system will, in most cases, not be acceptable for a hot water system. It is common for piping and construction materials, as well as the water being conveyed, to be seriously affected by aggressive environments and local conditions. In summary, it is still very much in the hands of the individual project adviser or installer to ensure that the plumbing products and materials selected for the application are in accordance with officialrequirements, will not be unduly affected or influenced by local factors and are correct for the application.
As well as deciding what is an acceptable plumbing product or material, the water authority or governing organization must set standards for the level of training attained by the installation personnel, a point that cannot be over-emphasized. In some countries, for reasons of economy, transport, proximity to manufacturing plants or restricted access to international markets, the choice of available materials for plumbing products and piping systems is often limited. Socioeconomic reasons may also dictate the quality and standard of plumbing in domestic dwellings.
10.3 Metallic and non-metallic materials used in pipework
There are two families of materials available for water pipework systems: metallic and non-metallic materials. Of these the most commonly used materials for drinking-water supply piping are galvanized steel or iron, copper, polybutylene, unplasticized polyvinylchloride (PVC), chlorinated polyvinylchloride (CPVC) and polyethylene (PE). Metal alloys, which far exceed the performance specifications of their respective parent materials, are also widely used. New materials and construction technologies are continually being developed for the building industry and the plumbing industry. Without some form of control at the respective levels within the plumbing and building industries it would be easy for unscrupulous manufacturers to use inferior materials to the detriment of installers and end-users. This can ultimately damage the environment and the health of the community and lead to greater costs later when systems fail prematurely.
10.3.1 Galvanized steel or iron
Galvanized steel or iron was the traditional piping material in the plumbing industry for the conveyance of water and wastewater. The term “galvanizing” once referred to hot dipped galvanizing, in other words total immersion in molten zinc after pretreatment cleaning. This technology afforded a reasonable level of internal and external protection to the metal pipe. In more recent times, the use of electroplating technologies has provided a more attractive external finish, but little or no internal protection. Although still included in many codes of practice throughout the world, the popularity of galvanized piping is declining. It is still being used extensively in the fire protection industry, but overall there are increasing limitations on how and where galvanized piping may be used. Internal and external corrosion is a particular problem where galvanized steel or iron piping is connected to dissimilar materials, such as copper alloy (brass) in taps and valves. Internal corrosion can add iron, which causes an undesirable taste and may also cause unsightly precipitation of iron salts on clothes. Aesthetic guidelines contained in the WHO Guidelines for Drinking-water Quality address these matters.
The use of galvanized steel or iron as a conduit for drinking-water is a greater problem where the water flow is slow or static for periods of time due to rust discoloration caused by internal corrosion. Galvanized steel or iron piping may also impart an unpalatable taste and smell to the water conveyed under corrosive conditions. Galvanized steel piping systems are generally accepted for outdoor use, but because of the size or bulk of the pipe and fittings, and the inflexibility of such systems overall, the material is not desirable for internal water plumbing. Galvanized pipe is heavy to handle and is generally joined by threading and screwing the components together. This is a lengthy procedure when compared to the assembly of competing non-metallic pipework systems.
10.3.2 Copper tubing
Copper tubing is extremely flexible in the hands of a competent installer and smaller in overall diameter than the equivalent galvanized steel pipes and fittings. Corrosion can be a problem, though usually to a lesser degree than with galvanized steel; care must be exercised to avoid contact with dissimilar metals.

When installed, all taps and water delivery outlet fittings should have an adequate clearance between the water outlet and the spill level or water overflow level of the fixture being served. It is possible for the overflow on any fixture to become blocked, which would compromise the air gap by not leaving the correct clearance. In situations where a portable or flexible hose or tube is attached to the water outlet, and an air gap cannot be provided, an appropriate backflow prevention device should be installed in the pipework supplying the fixture.
Local usage and customs should be considered when assessing plumbing requirements. An example is the choice of pedestal toilet bowls or squats. It may also be necessary to conduct training sessions in the use of particular fixtures to ensure that they are maintained in a satisfactory and hygienic state. In some areas it is customary to provide a drinking-water supply tap adjacent to the toilet fixture to facilitate personal ablutions. In such cases strict precautions must be taken to prevent contamination or cross-connection with the drinking-water supply system.
10.7 Sanitary fixtures
Sanitary fixtures should be durable, smooth and impermeable to water. There should be no hidden surface that can become fouled or polluted. Both internal and exposed outside surfaces should be accessible for cleaning. The most common and most economical material for domestic fixtures such as toilet bowls, urinals, and washbasins is vitreous china. For more durable day-to-day use in kitchen sinks and laundry tubs, stainless steel is recommended, but enamelled pressed steel and suitable plastic materials may be acceptable.
Plastics are commonly used for bathtubs, shower trays, laundry tubs, cisterns, washbasins and toilets and are often reinforced with fibreglass for extra strength and durability. Plastic materials, although generally durable in themselves, are readily prone to surface damage such as scratches and cuts. Stainless steel is a preferred material for plumbing fixtures where there is a risk of damage from users, such as in institutions and public amenities. Stainless steel is currently the only suitable choice in commercial or industrial food preparation areas.
10.8 Concrete products
The manufacture of plumbing products of any kind is expensive because of the capital investment in plant and the associated tooling. Unless high production volumes are anticipated, it is often more economical to import such items. To save foreign currency, materials such as concrete can be used for the local manufacture of fixtures for some domestic applications. These products are inferior to those discussed above, but they may be a realistic option. Ideally, concrete products should be designed so that angles, both internal and external, are rounded for ease of cleaning, and outlet pipes may be integrally cast into the body of the fixture. Concrete fixtures should be restricted to shower trays and baths, and possibly laundry fixtures such as troughs. It is recommended that concrete fixtures be cast in place wherever possible to eliminate the need for transportation. Concrete should not be approved for kitchen or food preparation sinks or benches. Local codes should cover all probable issues involving concrete fixtures, general design principles, etc., and also specify the proportions of sand, aggregate, cement and water required with general mixing, placement and finishing instructions. Preliminary investigations should ascertain the availability of local materials of the appropriate quality to ensure that the products can be produced satisfactorily. Concrete products cannot be made completely impervious; surface treatments such as ceramic tiles are sometimes used to address this problem.

Tentang Hidup Saya :
Saya lahir di Plaju, 39 tahun yang lalu. saya besar dan kuliah di Palembang. Saya bersekolah dasar di SD Yaktapena I Plaju (1978-1984) , dan masuk ke SMP Negeri 15 Palembang (1984-1987) dan saya masuk SMA Yaktapena I Plaju dan kelas dua ambil jurusan A1 (1987 - 1990) dan setelah lulus SMA , saya masuk ke Perguruan Tinggi tahun 1990 di Jurusan Teknik Mesin Fakultas Teknik Universitas Sriwijaya Palembang.
Dan tamat dan Wisuda tanggal 29 February 1996 ditahun kabisat. Setelah tamat kuliah saya bekerja dari April 1996 sampe sekarang di beberapa buah perusahaan yang ada di Indonesia sampe sekarang
Tentang Kehidupan Percintaan Saya,
Tentang Kehidupan Percintaan Saya,
Saya pertama kali pacaran ketika SMP kelas III, tapi kalau suka sama cewek dari SD kelas 6. Banyak yang bilang saya playboy tapi saya ketawa aja..karena pacar-pacar saya bisa dihitung dengan jari.. Karena saya pun nggak berani ngatakan cinta sama cewek yang saya sukai karena takut ditolak. Karena saya punya banya pengalaman ditolak sama cewek.
Saya punya prinsip kalau punya pacar harus cantik dan manis dan mirip artis. tapi kalau istri cantik dan menurut saya, cantik agamanya, tapi kalau cantik muka itu relatif (baca kutemukan istriu di malam Nisfu Sa'ban).
Saya mulai pacaran SMA kelas 1 dan maaf saya tak mungkin menyebutkan nama pacar saya sekarang takut marah dia bila dia membaca mengenai ini. Tapi dia tinggal di Depan Patra Jaya Plaju, dan anak SMA 8 Palembang. Tapi awal pendekatan ke dia yach dari sejak SMP kelas II. Setelah putus sama pacar pertama saya, dan dapat pacar lagi dan ini anak masih SMP kelas III dan saya waktu itu kelas II SMA. setelah putus dengan cewek ke dua saya, saya pun berusaha mendekati gadis-gadis teman SMA saya baik itu teman sekelas tapi tetap nggak dapat juga he..he..he... dan kuliah pun saya berusaha mendekati cewek adik tingkat dari Teknik Kimia tapi nyatanya tidak dapat juga..Hingga tamat kuliah saya nggak punya cewek dan ketika masuk kerja di Bontang, saya dekat dengan cewek lagi.. Dan dia ini anak tetangga dimana dekat rumah Wak saya di HOP III Bontang. jadi ketika kuliah aku punya pacar sebanyak 2 orang, tapi yang terakhir anak baru tamat SMA dan kuliah di Jogja..Ya itulah namanya pacaran sama anak SMA , akhirnya putus karena dia ternyata dalat yang lain di sana. Jadi pacar saya ada 5 orang dan yang terakhir saya jadikan istri.

Jadi pacar saya ada 5 orang dan yang terakhir saya jadikan istri.
Dan tahun 1999 saya menikah dengan istri saya sekarang, dan dikaruniahi 2 orang anak laki-laki.
Tentang Hobby Saya,
Hobby saya adalah main Bulu tangkis, Main Volly, main tenis meja, main tenis lapangan. Nonton bola juga saya hobby tapi saya nggak pandai main bola. Kesebelasan Kesukaan saya untuk klub luar yach Manchester United, Kalau Negara nya Indonesia dan Inggris, kalau klub lokal yaitu PSPS dan Sriwijaya FC.
Kalau hobby lain , saya hobby nyanyi dan suka karaoke dan juga saya hobby photografy..saya suka photo-photo obyek yang menurut saya bagus. Dan kadang saya diminta juga untuk jadi tukang photo di kegatan-kegiatan di tempat tinggal saya.
kalau lagu yang biasa saya nyanyikan adalah : lagi Kahtna, Dewa, Once, Slank, Kerispatih, Peter Pan, Ada Band.. Tapi sekarang ini saya lebh suka bawain lagunya Kerispatih..Karena menurut hemat saya vokal saya cukup pas dengan si sammy. Tapi vocalist yang Kerispatih sekarang kayaknya kurang bisa menyesuaikan dengan vokalist yang terdahulu. Memang kuakui vocal dan improvisasi Sammy sangat baik.
Tentang Pekerjaan saya,
Saya punya pengalaman kerja hampir 14 tahun, baik di bidang Oil & Gas, Pulp & Paper, Oil Palm Plantation and Factory ataupun Rubber Factory. Tapi walaupun beda-beda pekerjaan dan posisi tapi saya lihat semua yang dikerjakan sama yang berbeda adalah system kerja dan spec yang dipakai.
Saya bekerja di Lingkungan Project LNG selama hampir 3 tahun dan sudah cukup paham dengan apa yang ada di dalam sebuah LNG Plant. dan semua ilmu yang saya dapatkan ketika saya bekerja di dalam lingkungan PT. Bada NGL Co. Bontang..
Adapun perusahaan dimana saya bergabung selama saya bekerja di Lingkungan PT. Badak NGL Co Bontang :
1. PT. Citra Panji Manunggal (PT. CPM) anak perusahaan Medco Energy, sbenarnya mereka ini specialisasinya ke pipeline project tapi waktu itu kayaknya dapat project Maintenance. Saya bekerja dari April 1996 - December 1996 sebagai Scheduller ..
2. PT. Summa Prakarsa Coorporation (Supraco), man power supply untuk project Train G , tapi pada sadarnya kami diperbantukan di Facilities Engineering Technical Department, sebagai Mechanical Engineer (Piping & Static ). Saya bekerja dari April 1997 - Maret 1998. Tugas saya membuat Piping Plan Layout, Isometric Layout, Equipment Layout, Bill of Materials, masuk vesel keluar vesel pada saat shutdown Train.
Yang sering saya masukin adalah vesel 1- C - 2 dan 1 - C - 5 dan sering saya naik adalah di 5-E-1, kalau yang lainnya hanya via visual saja..
3. PT. Summa Prakarsa Coorporation (Supraco), man power supply untuk project Train G , tapi pada sadarnya kami diperbantukan di Facilities Engineering Technical Department, sebagai Mechanical Engineer (Piping & Static ). Saya bekerja dari Oktober 1998 - Oktober 1999. Tugas saya membuat Piping Plan Layout, Isometric Layout, Equipment Layout, Bill of Materials, masuk vesel keluar vesel pada saat shutdown Train. Sama seperti halnya dengan sewaktu kerja di PT. Supraco.. Istilahnya ganti bendera doang tapi tugasnya sama dan lokasi kerjanya sama.
Setelah sekitar hampir 3 tahun saya bekerja di Bontang, akhirnya saya memutuskan untuk keluar dari Bontang dan mencari pekerjaan di Riau dimana istriku tinggal. Tapi itulah suatu keputusan yang sangat fatal bagi karier hidup saya dimana saya ada kesempatan untuk bekerja di PT. Badak NGL Co. sebagai Mechanical Engineer tapi watu itu emosi saya nggak stabil dan pengen dekat dengan istri saya. kebetulan waktu itu kami baru menikah. Itulah emosi sesaat dimana kalau saya tunggu aja hasil pengumuman dari PT. Badak NGL Co, tentunya kehidupan saya nggak seperti sekarang ini. Tapi sudahlah semua sudah terjadi dan tak akan terulang lagi. Walau sedih kurasakan tapi aku harus ambil sikap agar dekat keluarga.
Setelah Keluar dari Bontang Kalimantan, saya pun dapat kerja di Riau. Dimana saya mendapat kerja di PT. Pec- Tech Indonesia sebagai Mechanical Engineer dan saya bekerja dari Maret 2000 - Juni 2001.
Kerja saya mendesign monorail, mendesign casing untuk motor, mengurusi document-document project, megawasi pekerjaan lapangan, berkoordinasi dengan vendor . Waktu itu projectnya adalah Upgrade Pulp Machine 1 dan 2 serta pembangunan Pulp Machine 3 di lingkungan PT. Riau Andalan Pulp and Paper.
Di perusahaan ini banyak sekali orang India entah dari mana saja. mereka masuk dan bekerja sebagai atasan
Saya pernah hampir mati sewaktu bekerja di sini dimana ceritanya sewaktu itu, saya sedang mengawasi pekerjaan di dalam cerobong untuk Pulp Dryer dengan pekerja sebanyak 3 orang dari PT. Truba Jurong Engineering sewaktu shutdown plant. Untunglah kami mendengar ada suara mechine dihidupkan jadi seketika kami berlari menuju manhole yang ada di atas dan untuk manhole nya cukup besar sehingga badan kami bisa menyangkut di manhole. Kalau tidak menyangkut mungkin tubuh kami sudah disedot ke dalam machne pengering pulp tersebut. Kami pun berteriak-teriak agar machin tersebut di hentikan.
Syukur Alhamdullillah , Allah masih menyelamatkan diri kami. Tapi yang buat saya jengkel bos kami yang kulkarni namanya pura-pura menganggap itu tak terjadi apa-apa. dan cuek aja dan tidak merasa bersalah atas kejadian tersebut.
Setelah saya meninggalkan PT Pec Tech Indonesia Pangkalan Kerinci, akhirnya saya berlabuh di salah satu perusahaan perkebunan yang ada di Medan. Namanya PT. Tolan Tiga Indonesia yang merupakan group dari SIPEF Belgia. Dan Perusahaan ini mempunyai 25 anak perusahaan yang ada di seluruh Indonesia, yaitu di Sumatera Utara, Bengkulu, Jawa Barat, Sumatra Selatan. Posisi saya Assistant Technik / Mill Assistant. Dimana pekerjaannya sebagai supervisor untuk pengwasan pekerjaan di lapangan atau di pabrik.
Untuk pertama kalinya saya ditempatkan di Muko-Muko Bengkulu.
1. PT. Agro Muko Crumb Rubber Factory, (January 2002 - Maret 2003)
2. PT. Simpang Kiri Plantation Indonesia (Maret 2003 - April 2004)
3. PT. Bandar Sumatra Indonesia (April 2004 - June 2005)
4. PT. Tolan Tiga Indonesia "REHABILITATION AND RECONSTRUCTION ACEH" (June 2005 - Sept 2005)
Banyak hal yang menarik yang mau saya ceritakan sewaktu bekerja di Tolan Tiga Indonesia, tapi kayaknya terlalu banyak jadi singkat cerita, saya resign dari PT. Tolan Tiga Indonesia karena saya tidak puas dengan apa yang saya dapat di sana yaitu komitmen. Karena sewaktu saya di tempatkan di Banda Aceh, saya dijanjikan aan mendapatkan uang makan perhari Rp. 80 ribu karena saya mandah di sana, dan mendapatan uang sewa rumah dan mendapatkan uang transport. Tapi apa yang saya dapat trnyata uang makan saya dikasih sekitar 300 ribu/bulan, uang transport 500 ribu/bulan dan uang sewa rumah 500 ribu perbulan. Dan ditengah kondisi waktu itu 6 bulan setelah terjadinya Tsunami Aceh.. Dan ditengah kondisi masih ada gempa, panas dan angn kencang..dan harga-harga makan cukup mahal dimana 1 hari saya bisa kena 40 ribu/hari.
Untuk mengirit pengeluaran saya setdak-tidaknya makan indomie goreng hampir setiap makam dan berjalan kaki ke setiap lokasi proyek di Lampo Daya dan Punge Jurong. Makanya dengan kodisi yang seperti itu dan tidak adanya kebijaksanaan dari Perusahaan Tolan Tiga Indonesia. Saya memutuskan untuk mencari pekerjaan lain. Saya kurang suka dengan orang yang tidak bisa menjaga komitmennya Dan saya pun berusaha untuk menjaga komitmen saya. Tapi karena tidak adana komitmen dari perusahaan akhirnya saya mencari pekerjaan lain di luar Banda Aceh, baik itu menghubungi teman-teman saya atau melalui internet.
Singkat cerita akhirnya saya dapat pekerjaan di Duri Riau dimana lokasinya dekat dengan tempat tinggal keluarga saya di Pekanbaru.
September 2005 awal mula saya bekerja di PT. TRIPATRA FLOUR CONSORTIUM Duri untuk Project Flexible Program Management di PT. Chevron Pacific Indonesia Duri.
Saya disini ditempatkan di Engineering Department - awal masuk sebagai Design Engineer - Piping dan Terakhir sebagai Senior Design Engineer - Piping & Mechanical. Saya bekerja di sini dari September 2005 - Mei 2009 dan pekerjaannya adalah membuat scope of work piping, estimate manhours, mambuat deliverable list, piping layout, equipment layout and section, isometric layout, bill of materials dan lain-lain yang hubungan dengan pekerjaan saya.
Saat ini saya masih bekerja di salah satu Perusahaan Engineering Consultant di Duri Riau..Areal kerja di Dalam Lingkungan Complek PT. Chevron Pacific Indonesia, tugasnya sebagai engineering consultant untuk project yang berhubungan dengan Tanki dan Pipa. Posisi Saya Senior Mechanical Engineer disamping pekerjaan Mechanical juga mengerjakan pekerjaan Piping. Tapi sebenarnya experences saya banyak di Piping Design Engineering tapi berhubung yang dapat posisi tersebut jadi mau tak mau diambil juga dan setidak-tidaknya dapat menambah ilmu mengenai mechanical.
Tapi sebentar lagi kontrak saya berakhir dan saya harus mencari pekerjaan baru lagi dan mau nya yang sesuai dengan bidang saya Piping Design tapi bila nggak ada juga , apapun pekerjaannya yang penting halal dan cocok gaji yang ditawarkan. Tolong bantuannya untuk mencarikan pekerjaan sebagai Senior Piping Engineer. ....

ALL ABOUT INTERNATIONAL VALVE'S STANDARDS
Here I enclosed the International standard of the valve that are using in the piping system. The valves selection is on the Client Spec. This information , I got when I seaching in http://www.engineeringtoolbox.com/.
And In that website you can get many information about the piping system and others.
This International Standard are API, DIN, ISO, ASME, ASTM, BS, GB, JB. Most of standards is from USA, Japan, British, Germany. If you confused you can dowload more in http://www.engineeringtoolbox.com/
Here the list of the Valve International base on the International Standards,
API - Valve Standards
An overview of the American Petroleum Institute - API - valve standards
Valve standards from API - the American Petroleum Institute:
• API SPEC 6D
Specification for Pipeline Valves. API Specification 6D is an adoption of ISO 14313: 1999, Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems.
• API 526
Flanged Steel Pressure Relief Valves. The standard is a purchase specification for flanged steel pressure relief valves. Basic requirements are given for direct spring-loaded pressure relief valves and pilot-operated pressure relief valves as follows: orifice designation and area; valve size and pressure rating, inlet and outlet; materials; pressure-temperature limits; and center-to-face dimensions, inlet and outlet.
• API 527
Seat Tightness of Pressure Relief Valves R(2002). Describes methods of determining the seat tightness of metal- and soft-seated pressure relief valves, including those of conventional, bellows, and pilot-operated designs.
• ANSI/API STD 594
Check Valves: Flanged, Lug, Wafer and Butt-welding. API Standard 594 covers design, material, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for two types of check valves.
• API 598
Valve Inspection and Testing. The standard covers inspection, supplementary examination, and pressure test requirements for both resilient-seated and metal-to-metal seated gate, globe, plug, ball, check, and butterfly valves. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant.
• ANSI/API 599
Metal Plug Valves - Flanged, Threaded and Welding Ends. A purchase specification that covers requirements for metal plug valves with flanged or butt-welding ends, and ductile iron plug valves with flanged ends, in sizes NPS 1 through NPS 24, which correspond to nominal pipe sizes in ASME B36.10M. Valve bodies conforming to ASME B16.34 may have flanged end and one butt-welding end. It also covers both lubricated and nonlubricated valves that have two-way coaxial ports, and includes requirements for valves fitted with internal body, plug, or port linings or applied hard facings on the body, body ports, plug, or plug port.
• ANSI/API 600
Bolted Bonnet Steel Gate Valves for Petroleum and Natural Gas Industries - Modified National Adoption of ISO 10434:1998.
• API 602
Compact Steel Gate Valves - Flanged, Threaded, Welding, and Extended-Body Ends. The standard covers threaded-end, socket-welding-end, butt-welding-end, and flanged-end compact carbon steel gate valves in sizes NPS4 and smaller.

API - Valve Standards
An overview of the American Petroleum Institute - API - valve standards
Valve standards from API - the American Petroleum Institute:
• API SPEC 6D
Specification for Pipeline Valves. API Specification 6D is an adoption of ISO 14313: 1999, Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems.
• API 526
Flanged Steel Pressure Relief Valves. The standard is a purchase specification for flanged steel pressure relief valves. Basic requirements are given for direct spring-loaded pressure relief valves and pilot-operated pressure relief valves as follows: orifice designation and area; valve size and pressure rating, inlet and outlet; materials; pressure-temperature limits; and center-to-face dimensions, inlet and outlet.
• API 527
Seat Tightness of Pressure Relief Valves R(2002). Describes methods of determining the seat tightness of metal- and soft-seated pressure relief valves, including those of conventional, bellows, and pilot-operated designs.
• ANSI/API STD 594
Check Valves: Flanged, Lug, Wafer and Butt-welding. API Standard 594 covers design, material, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for two types of check valves.
• API 598
Valve Inspection and Testing. The standard covers inspection, supplementary examination, and pressure test requirements for both resilient-seated and metal-to-metal seated gate, globe, plug, ball, check, and butterfly valves. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant.
• ANSI/API 599
Metal Plug Valves - Flanged, Threaded and Welding Ends.
